Hi Johannes

My wife has a PowerBook with exactly the machine you are looking for.
(Running Linux pb 2.6.24-19-powerpc #1 Fri Jul 11 21:37:37 UTC 2008 ppc 
GNU/Linux)

Therefore here the following info.

cat /proc/cpuinfo

 find /proc/device-tree/ -wholename '*sound/device-id' | xargs hd
00000000  00 00 00 23                                       |...#|

If you want the whole device tree, just tell me how to dump it and I will send 
it to you.

Best regards
